title: Effects of family structure on risk of institutionalisation of disabled older people in Japan.
abstract: OBJECTIVE
  To examine the relationship between family structure and the risk of institutionalisation of disabled older people.
  
  
  METHODS
  The participants were 286 disabled older people aged 65 or older who were eligible to receive formal care services under the long-term care insurance system in a town in western Japan. Family structure was categorised as living alone, living only with a spouse, living with a son, living with a daughter and living other relatives. The risks of institutionalisation were estimated by logistic regression analyses.
  
  
  RESULTS
  Participants living with a daughter had a significantly low odds ratio (OR) for institutionalisation (OR: 0.35, 95% confidence interval (CI): 0.13-0.93) and those living alone had a significantly high OR (OR: 2.31, 95% CI: 1.02-5.20), when compared to participants living with a son (regarded as the reference). The ORs of participants living only with a spouse and living with other relatives were 1.50 (95% CI: 0.59-3.79) and 0.66 (95% CI: 0.15-2.82), respectively.
  
  
  CONCLUSIONS
  Living with a daughter could reduce the risk of institutionalisation for disabled older people.
